hey guys...i got a CVA magbolt 150 in .45 caliber that i got a gun show last year. i finally got around to taking it out to the range to see how well the scope was sighted in. i shot it at 50 yds and it was dead on, but was rushed for time and didn' t shoot at 100. how much drop will i be noticing on a 100-125 yd shot with 150 grains of powder on a 180 grain XP mag. sabot?? im only using it for deer here in NC and was just wondering what kind of distance i' m gonna have with it. it' ll be my first witht black powder and i need a little coaching. thanks a lot.
